Championship and no poles? ever happen?

With Dale Jarrett winning the Cup championship and not scoring any poles in 1999, I was asked, has it ever happened before? Yep, five times, most recently, in 1991 when Dale Earnhardt won the Winston Cup Championship with four wins and NO poles. It also happened in 1983-Bobby Allison; 1980-Earnhardt; 1973-Benny Parsons; and 1950-Bill Rexford(The Stock Car Racing Encyclopedia)(11-14/21-1999)
